IMPROVEMENT IN WASTE-TRAPS FOR WASH-BASINS.

Specification forming part of Letters Patent No. 135,206, dated January 28, 1873.

To all whom it may concern.-

Be it known that I, HUGH H. CRAIGIE, of the city and State of New York, have invented an Improvement inWaste-Traps for Wash- Basins; and the following is declared to be a correct description thereof.

In Letters Patent No. 89,858, granted to me, a trap is shown adapted to being attached directly to the wash-basin and interposed between such basin and the wastepipe.

My present invention is an improvement upon aforesaid device; and consists in a floating valve applied at the discharge-aperture so as to close the same and prevent smell passing out of the waste-pipe in cases where the water has been siphoned out of the trap or where the water has evaporated.

In the drawing I have represented my improvement by a vertical section.

A portion of the bottom of the basin is shown I at a with the ferrule I) screwed into the trap d,

and having a flange, 2, for securing the same to the basin a. The plug 0, coupling h to the basin-overflow, coupling 70 to the sewer-pipe,

and screw-cap f to the trap are substantially the same as in the before-mentioned patent, and do not require further description. The partition 9 interposes between the sewer-pipe k and the thimble or ferrule b, and in this is the seat for the valve on. This valve is free to rise in the chamber a, but cannot escape into the sewer-pipe 7c, being too large. Hence, when said'valve rests upon its seat there is no opportunity for smell to escape from the sewer-pipe, whether the trap d contains water or not. The screw-stopper 0 gives access to the chamber a for cleansing the same or the valve m. 1

I claim as my invention- The valve m within the chamber n, in combination with the trap d and screw-ferrule b, substantially as and for the purposes set forth. Signed by me this 1st day of June, A. D.
